The Pythagorean theorem is a formula that you use for finding all sides of a right triangle. One situation you would use it would be when a girl is riding her bike out to her friends house she gets 5 feet away, and she remembers she had a gift for her friend she takes a short cut to her right and sees that it's in her bike basket. She goes back up and cuts through someones yard and gets back to where she was. 
 What you would do would be to
  1. First know your problem then know your equation.
  2. Next your equation is a^2+b^2=c^2
  3. Now all you have to do is solve.
